Arrowsign

Based on game build 714014 | Last updated: 2026-03-04

Overview​

The arrowsign prefab defines two related prefabs: arrowsign_post (the base post) and arrowsign_panel (the writable sign panel). The post supportshammering, burning, rotation, and loot drops, while the panel handles writing and is visually linked to the post. The component logic is embedded within the prefab constructors (fn and panelfn), not a standalone component class.

Usage example​

-- Typical prefab instantiation (handled internally by DST)
-- The player places the arrow sign using the builder menu.
-- Writing and interaction occur via the `inspectable` and `writeable` components.

-- Example: Checking if a placed arrowsign is burnt
if sign:HasTag("burnt") or (sign.components.burnable and sign.components.burnable:IsBurning()) then
    print("Sign is burnt")
end

Dependencies & tags​

Components used: burnable, lootdropper, savedrotation, workable, inspectable, writeable, soundemitter, animstate, transform, minimapentity, network

Tags added: structure, sign, directionsign, rotatableobject, _writeable (temporary, removed on master simulation), burnt (added conditionally on load if saved as burnt)

Properties​

No public properties are defined in the constructor logic. State is managed via component properties (e.g., workable.workleft, burnable.burning) and saved in data tables during save/load.

Main functions​

No public methods are defined directly on the prefab instance. Functionality is delegated to attached components and registered callbacks.

Callback functions (internal)​

onhammered(inst, worker)​

  • Description: Handles hammering the sign post; extinguishes fire, drops loot, spawns collapse FX, and removes the entity.
  • Parameters: inst (entity), worker (player entity performing the hammering).
  • Returns: Nothing.
  • Error states: Expects burnable and lootdropper components to exist.

onhit(inst, worker)​

  • Description: Plays a "hit" animation when the sign is being worked on (if not already burnt).
  • Parameters: inst (entity), worker (player entity).
  • Returns: Nothing.

onsave(inst, data)​

  • Description: Saves the burnt state (data.burnt = true) if the sign is currently burning or burnt.
  • Parameters: inst (entity), data (table to be serialized).
  • Returns: Nothing.

onload(inst, data)​

  • Description: Restores the burnt state by triggering onburnt callback if data.burnt is true.
  • Parameters: inst (entity), data (table loaded from save).
  • Returns: Nothing.

onloadpostpass(inst, newents, data)​

  • Description: Applies saved rotation using savedrotation:ApplyPostPassRotation.
  • Parameters: inst (entity), newents (table of loaded entities), data (save data with optional savedrotation.rotation).
  • Returns: Nothing.

onbuilt(inst)​

  • Description: Plays the "sign_craft" sound when the sign is built via crafting/hammer.
  • Parameters: inst (entity).
  • Returns: Nothing.

Events & listeners​

  • Listens to: onbuilt — triggers onbuilt callback to play sound.
  • Pushes: None directly; events are handled via attached components (workable, burnable, etc.) and internal callbacks (OnSave, OnLoad, OnLoadPostPass).
